HEALTH & SAFETY Cryogenic Liquids Safety

Hazards Cryogens can present one or more of the following hazards: Extreme Cold: Cryogenic liquids and their associated cold vapors and gases can produce effects on the skin similar to a thermal burn. Brief exposures can damage delicate tissues, such as the eyes. Prolonged exposure of the skin can cause a cold burn and frostbite.

03-005 MAGNET SAFETY - Environmental Health and Safety

1.2.1 Liquid helium is used to maintain the magnetic field in NMR and MRI systems. Liquid nitrogen is also used. Both liquids are extremely cold (liquid helium -452 F, liquid nitrogen -320 F), colorless, and odorless. A sudden boil-off of cryogens and accompanying loss of magnetic field (called a “quench”) poses a significant safety risk.
